*
Hazard ratios (HRs) with 95% confidence intervals (CIs) given for Cancer of the Prostate Risk Assessment (CAPRA) as a continuous variable (4-6 treated as equal to 4) and at each level compared with a CAPRA score of 0 as a referent. Five-year actuarial biochemical recurrence-free survival calculated via Kaplan-Meier analysis.
